PSQL_EDITOR: Fighting with Sublime Text under Windows
This supposed to be just a short TIL entry about PSQL_EDITOR variable. While trying to figure out all possible pitfalls, I’ve decided to write a full blog post. You may skip to the summary though. All tests done on Windows 10 with PostgreSQL 12 installed. As you know, PostgreSQL ships with an interactive console tool […]
Building PostgreSQL (x86, x64) and OpenSSL using MSYS2 and MinGW under Windows

That’s true nowadays you won’t find binaries or installations of PostgreSQL without […]
